3-General Safety Instructions
1.Specular Reflection
There are often numerous secondary laser beams produced at various angles in the output port of the laser. These divergent beams are produced when the primary beam of laser refects off a smooth surface, and they are called specular reflections. Although these secondary beams may be less powerful than the total power emitted from the primary beam, the intensity may be great enough to cause damage to the eyes and skin as well as surface of materials.
WARNING:
◎ You must exercise caution to avoid/minimize specular reflections as these laser radiations are invisible!
2.Safety Instructions of Accessories
The photosensitive elements integrated in laser-related optical accessories may be damaged by laser exposure, such as: video cameras, photomultipliers, and photodiodes. Attention should be paid to related device protection.
WARNING :
◎ The Maxphotonics MFSC laser light is strong enough to cut or weld metal, burn skin, clothing and paint. In addition, this light can ignite volatile substances such as alcohol, gasoline, ether and other solvents. During the operating process, the fammable materials around the laser must be isolated.
3.Optical Operating Instructions
We strongly recommend that you read the following procedures before operating the laser:
1.Never look directly into the laser output port when the power is turned on.
2.Avoid positioning the laser and all optical output components at eye level.
3.Equip with laser beam casing.
4. Make sure to remove the tail cover of the laser output head before the laser is turned on, otherwise it will cause irreversible damage to the laser fber output head.
5.Ensure that all personal protective equipment is suitable for the output power and wavelength range of the laser.
6.Use the laser in a room with access controlled by door interlocks. Post warning signs. Limit the safety areas to operate the laser.
7.Please do not operate the laser in darkened environments.
8.Do not turn on the laser without an optical coupling fber or an optical output connector.
9.Carry out commissioning, calibration and focusing at low output power and then increase the output power gradually when the calibrating and focusing work is done.
10.Do not install or detach cutting heads or collimators when the laser is active.
11.Make sure that the laser is shut down and the power is off before you install or detach cutting heads or collimators.
12.If the equipment is operated in a manner not specifed in this document, the protection devices and performance of the equipment may be impaired and the warranty will be voided.
CAUTION:
◎ The output of the laser is delivered through a lens with an anti-reflection coating. If the backward-stage light path of your laser has the optical lens, please strictly inspect the lens of the output head and the backward- stage lens of the laser, and ensure that there is no dust and any other impurity on the lens.
Please note that any macroscopic attachment may cause extreme damage to lens or burn the laser or any backward-stage light path equipment.
◎ For cleaning instructions of the lens, please refer to the “Optical Fiber Connector Inspection and Cleaning Guide”.
◎ Hot or molten pieces of metal may be produced when the laser is under operation. Exercise caution if debris is produced in operation.
◎ When you carry out commissioning and calibration of the laser output, you must set the laser output at low power level and then gradually increase the output power during checking the quality of the light spot emitted from the laser via an infrared viewer.
WARNING:
◎ Make sure that the individual protective equipment meets the output power and wavelength range of the laser.
◎ Never look directly into the optical fber or the collimator, and make sure you wear the safety protective glasses in each operation.
4.Electrical Operating Instructions
We strongly recommend that you read the following procedures before operating the laser:
1.The power supply voltage of the laser equipment is three-phase alternating current 360-440VAC, 3P+PE. The laser equipment needs to be properly grounded during installation and installation. The external cables of the cabinet must be placed in metal trunking or metal pipes during installation. Pay attention to the safety of electricity during use to prevent electric shock injury .
2.When disassembling the laser, turned off the power first . If electrical injury occurs, corrective measures should be taken to prevent secondary injury. The correct treatment process: turn off the power, release the personnel safely, call help, and accompany the injured.
3.The equipment does not have any part which can be maintained by operators, and all the maintenance operations must be finished by the professionals of Maxphotonics.
4.To prevent electrical shock, do not remove enclosure, detach the laser without permission and damage the relevant signs. Any product with unauthorized dismounting shall not be subject to warranty.
WARNING:
◎ The input voltage of the laser is triple-phase AC current (360-440VAC, 3P+3E), which may cause risk of electric shock. All the relevant cables and connection wires have potential hazards.
5.Environment Conditions and Precautions
For ensuring the safety of the laser working area, suitable enclosures shall be applied, including but not limited the laser safety signs and the interlocking devices. Corresponding operators must be trained and examined and know the normal safety specifications for operating the laser.Meanwhile, it is important that the output components shall not be installed at eye level.
Because of interaction of the laser and the metal material, the radiation of high level ultraviolet light or visible light may be produced. Make sure that the laser is provided with the protective cover to prevent the eyes or other parts of human bodies from damage by radiation.
We recommend that you comply with the following operating measures to prolong the service life of the laser:
1.In order to ensure a good operating environment of the laser, reduce the risk of condensation, reduce the probability of failure, and prolong the service life.
It is strongly recommended to configure the air-conditioned room of the laser in advance. The air-conditioned room should be spacious enough to facilitate internal maintenance. It can guarantee the minimum free space around the laser is 1.0m. If space is limited, the air-conditioned room needs to be designed to be easy to remove and install.
2.It is necessary to provide suffcient installation space for the air-cooled water cooler, and to ensure suffcient water cooler exhaust. The minimum free space of the top of the air-cooled water-cooled fan is 1.5m, and the side plate of the air flter is 1m away from the wall.
3.It is forbidden to place the air-cooled water-cooled machine in the laser air conditioned room. Because the air-cooled water-cooling machine discharges a lot of hot air, the room temperature will rise rapidly, and finally the heat dissipation will be poor, causing the water-cooling machine high-pressure alarm and laser condensation alarm.
4.Do not expose the laser to a high moisture environment.
5.The device is equipped with cooling fans. Make sure that there is sufficient airfow to cool the laser, any objects or debris that cover the ventilation holes must be removed at all times.
6.Operation at higher temperature will accelerate aging, increase threshold current and lower slop efficiency. If the device is overheated, stop operations and contact Maxphotonics.
7.Ensure that the work surface is properly vented. There may be gases, sparks and debris generated from the interaction between the laser and the work surface, and they could pose additional safety hazard.
CAUTION :
◎ The device may be damaged with incautious operation.

3-Cleaning Procedures
1.Switch off the laser power, and place the key switch on position of ”OFF”
2.Cleaning protective lens with swabs
1.Rotate the black protective sleeve of the connector clockwise, place the inner or outer surface under a microscope of 20 times and make it clear. After careful observation, determine the specifc position of the dust particles, open the alcohol bottle cap and gently press the alcohol bottle mouth makes a small amount of alcohol ooze out, completely immerse the round cotton swab in alcohol, and then lightly swab the cotton swab to remove excess alcohol. Use a cotton swab to wipe the dust particles straight in the direction of the operator’s body.
The force should be light. After each wiping, the cotton swab can be rotated 180° and then wiped with the other side. After wiping for 2 times, the cotton swab is scrapped. Note that it is not allowed to circle. Or wipe back and forth to prevent dust particles from contaminating other areas or cotton swabs directly scratching the surface.After all cleaning, it is necessary to observe under the microscope again whether the surface is clean.
Endface may be damaged
2.Check the inner wall of the protective guide tube if there is obvious foreign matter with the microscope. If the foreign matter can be cleaned with a double sided glue stick, then use a cotton swab to wash the alcohol for further cleaning.
After the protective guide tube is dried, directly put on the connector.
3.Cleaning method for quartz rods
If fnd that the internal quartz rod is dusty or dirty, you can open the lens to clean it. The specifc steps are as follows:
1.Rotate the black protective sleeve, dust cap and protective lens at clockwise, first wipe the circumference and thread surface of the entire connector lens piece with an optical cleaning cloth and alcohol;
2.Put the quartz rod under a 20x microscope and make it clear. After careful observation, determine the specific location of the dust particles and clean according to the method of 3.2.1. For dust particles on the side of the fused quartz rod, use a pointed cotton swab to clean along the circumferential surface.
After all cleaning, confrm under the microscope whether it is clean, including the chamfered area. Finally, wrap it on the table with a non-woven fabric, and then continue other work to prevent the dust from contaminating the end face and side of the fused silica rod again;
3.Along the grain of the surface of the metal part, gently rotate the lens piece back to the metal part and confrm that it is in place. Place the black protective sleeve on the connector.
IMPROTANT：
◎ Do not reuse a lint-free optical wipe or swab;
◎ Do not touch the protective lens of the fber connector;
◎ Do not blow directly, or else new dirty will be brought;
◎ Do not touch the tip of the cleaning swab with your fngers;
◎ Cleaning is necessary before place the protective cover and s leeve;
◎ Never blow air directly at the surface, because you could imbed
contaminants into the surface. Always blow across the surface;
◎ If the fber connector could not be installed in optical system immediately, please cover it with the protective cap cleaned with compressed air;
◎ Be sure to operate in a Class 1000 clean environment
